B707 over SFO with #4 engine missing and wing on fire and outboard section missing. There is a photo taken by a passenger of the burning wing. Aircraft successfuly diverted to an airforce base.
Engine fires typically burn themselves out without burning into the wing or fuselage once the fuel is shutoff. The bigger problem is if the pylon to engine fireshield has been breeched or the engine fire bypasses the shield and reaches the fuselage or wing (with little airflow to stream it in back of the plane)
